Hope you are keeping safe in 2020!
Social distancing is one of the top recommended ways to stop the spread of CoViD-19 disease by the WHO. It is also important to make sure that this is enforced at all times as people can be absent minded or accidentally come close to each other. This is especially true in crowded areas like hospitals and work places.
To mcontinuously onitor and enforce this I have come up with a simple ESP based device. The idea is to provide everyone working in one location with this device that will continuously monitor if there is a similar device around them. If there is another similar distance around them close to a preset distance of roughly 1 meter or 3 meters according to the regulations in the location and use of PPE, the device will light up or ring loudly alerting the wearer to move away from the location or to be extra cautious.
